What’s PET sandwich panels?
PET sandwich panels are made from 100% recyclable eco-friendly materials. PET is a rigid closed-cell foam similar to XPS foam. It is typically bonded together with FRP and CFRT skins. The density of PET foam ranges from 50 to 250 kg/m³. Thicknesses range from 10 to 150 mm. It is widely used for wall panels and flooring in RVs and truck bodies.

Características
PET sandwich panel is a globally recognized 100% recyclable structural plastic core material made from foamed polyethylene terephthalate (PET). Its surface can be seamlessly laminated with continuous fiber-reinforced thermoplastics (CFRT), glass fiber-reinforced plastics (FRP), carbon fiber, aluminum sheets, or plywood to form lightweight, high-rigidity composite panels.
PET offers outstanding properties including low weight, high strength, zero water absorption, excellent corrosion resistance, and long-term durability, even in harsh wet or marine environments. Compared to traditional timber and aluminum, it is more environmentally friendly, significantly stronger and lighter, and achieves full closed-loop recyclability, making it the superior green core material widely used in refrigerated transport, marine engineering, wind turbine blades, and modern construction.
